Today i was creating a configuration file, in the past, i accessed configuration as a dictionary, but this time, i think about changing that. The follwing code creates dynamic attributes with the objects keys recursively.
But first, i'll show the json object:
{
"key": "value",
"list": [
"a",
"b",
"c",
1,
{
"key": 1
}
],
"object": {
"key": {
"key": 1
}
}
}
On the conversion we have 3 cases:
- lists
- dicts (new object)
- bool, int, float and str
import json
class AppConfiguration(object):
def __init__(self, data=None):
if data is None:
with open("cfg.json") as fh:
data = json.loads(fh.read())
else:
data = dict(data)
for key, val in data.items():
setattr(self, key, self.compute_attr_value(val))
def compute_attr_value(self, value):
if type(value) is list:
return [self.compute_attr_value(x) for x in value]
elif type(value) is dict:
return AppConfiguration(value)
else:
return value
Now the key, value pairs are attributes - objects.
instance = AppConfiguration()
>>>instance.key
'value'
>>>instance.list[4].key
1
>>> instance.object.key.key
1
